i'm equivocating, but still... don't quote me.
Not necessarily. Certainly the 68mm dimension is nearly universal on current road bikes, but the 107mm, which is for the spindle (axle) length, is not. In fact, a 107mm spindle seems rather short for most cranksets, other than single chainring cranks. Typically, most double square taper cranks would use a spindle ranging from 108 to 115mm, and most road triples would use a spindle ranging from 115 to 127mm.

Here's Sheldon Brown's database on bottom bracket compatibility with cranksets. It's not complete, but it's as good a source as I've found on this subject:
